Skype for Business Server wanted to improve people's 1-to-1, and their 1-to-many (multi-party) conversations and meeting experiences. Newer technology, VbSS, will make use of User Datagram Protocol (UDP). Screen-sharing uses the remote desktop protocol (RDP), which is great at creating thousands of 1-to-1 sessions between people's computers. The difference between VbSS and traditional screen-sharing has to do with the underlying protocols used, and what they excel at. Video-based Screen Sharing, or VbSS, grew out of Lync screen-sharing. VbSS is included with Skype for Business Server 2019. Video-based Screen Sharing (VbSS) in Skype For Business Server 2015 is now available for download: Skype for Business Server 2015 Cumulative Update KB3061064.
